Une méthode semi-explicite pour la simulation des problèmes d'impact avec frottement

Abstract : We are interested in the modeling of frictional impact problems. This Note presents an approach which reconciles the speed of resolution (semi-explicit calculation) and the accuracy of contact modeling by the bi-potential method. This method deals with the unilateral contact and the friction in a coupling way via a contact bi-potential. It leads to an implicit resolution at the contact zones between deformable bodies with or without friction. The proposed method is compared with an implicit one both implemented in the code FER/Impact and with a pure explicit method available in the industrial code LS-DYNA.
